Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It transparently describes the pagination mechanism and cursor flow, which is valuable. However, it does not mention whether the operation has side effects (e.g., consuming/acknowledging events), preconditions (e.g., valid ctx), or what happens on empty results. This partial disclosure is insufficient for a tool with no annotation safety hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
